Space Quizzes

Mercury, Mars & Solar System Science

Compare objects and events at very different scales in a 10-question space quiz. You will encounter the asteroid belt, planetary temperature and density, Mercury's orbit, the first lunar landing, stellar explosions and black holes. Use the distinction between appearance and physical properties to guide you, especially where a question concerns brightness rather than size or temperature.

Stars, Meteorites & Space Physics

Explore stars, space rocks, planetary systems and an orbiting telescope in this 10-question quiz. Topics include the Sun's classification, stages of stellar evolution, moons, dwarf planets and the relationship between rotation and orbital periods. A question about a liquid metal adds a wider science connection. Keep definitions precise when similar everyday words have distinct astronomical meanings.

White Dwarfs, Moons & Deep Space

Explore stellar remnants, brown dwarfs and nearby galaxies in a ten-question space quiz that also visits several familiar planetary moons. Topics include Deimos, Triton, a volcanic moon of Jupiter, a large moon of Saturn, a landmark space telescope and the discovery of Pluto. There is also one question about the radiotelephony spelling alphabet. Work out whether each question concerns a moon's parent planet, the properties of a star-like object or a historical discovery.

Apollo Missions, Planets & Their Moons

Explore the Solar System and the history of space exploration in ten questions. Identify planets from clues about their moons, orbits, rotational periods and axial tilt, then move on to the final crewed Apollo lunar landing, a Mars rover and early human spaceflight. A question about the discovery of pulsars broadens the scope beyond the planets. Pay attention to whether the subject is a planet, its satellite, a spacecraft or an astronomer.
